Elementary classes can enable students to master hypnosis techniques and have a preliminary experience and mastery of hypnotherapy.
The advanced class is aimed at students who have a certain foundation, so that students can face the master face to face and further improve themselves through face-to-face communication and live hypnosis demonstration.
No matter what form of training, it is unrealistic to master a skill in a few days. Need to be gradual, need to constantly improve in the application, haste makes waste.
As far as I know, there is distance training for hypnotists in China at present. You can lay a good foundation through distance learning, and then continue your studies through face-to-face teaching. The study time is relatively free and flexible, and you can also open a certificate from the Ministry of Labor if you pass the exam.
